Description

쿨링 파이프가 인서트 되는 냉각모듈 및 그 제조방법{a cooling module within cooling pipe and method thereof}[0001] The present invention relates to a cooling module having a cooling pipe inserted therein,

본 명세서는 발열체로부터 발생되는 열을 쿨링 파이프의 냉각수에 의해 열교환시켜 방열시키기 위한 쿨링 파이프가 인서트 되는 냉각모듈 및 그 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling module in which a cooling pipe for heat-dissipating heat generated by heat generated by a heating element by cooling water of a cooling pipe is inserted, and a manufacturing method thereof.

일반적으로, 다이캐스팅은 다이 주조라고도 하며, 임의의 주조 형상에 완전히 일치하도록 정확하게 기계가공된 강제(鋼製)의 금형(金型)에 용융금속(熔融金屬)을 주입하여 금형과 동일한 주물을 얻는 정밀 주조법으로, 그 제품을 다이캐스트 주물이라고 하며, 자동차 부품, 전기기기, 광학기기 및 계측기 등의 부품을 제조하기 위해 사용된다.In general, die casting is also referred to as die casting, and is a precision die casting method in which a molten metal is injected into a steel die machined precisely to perfectly match an arbitrary casting shape, In the casting process, the product is referred to as a die cast casting, and is used for manufacturing parts such as automobile parts, electric devices, optical instruments, and measuring instruments.

중력주조법은 용융 금속을 중력 방향으로 금형에 주입 및 응고시켜 주물을 생산하는 것으로서, 성형 방식과 설비가 간단하고, 조직이 강하고 기계적 성질이 높기 때문에 알루미늄(Al), 마그네슘(Mg), 구리(Cu) 등의 비철합금, 주철 또는 강철을 소재로 하여 피스톤, 슬리브, 크랭크 케이스, 실린더, 베어링 등을 제조하기 사용된다.The gravity casting method is to produce castings by injecting molten metal into the mold in the direction of gravity and solidifying it. Since the molding method and equipment are simple, the structure is strong and the mechanical properties are high, aluminum (Al), magnesium (Mg) ), A cast iron, or a steel, and is used to manufacture a piston, a sleeve, a crankcase, a cylinder, a bearing, and the like.

기지국이나 중계기와 같은 옥외용 통신 시스템은 다수의 고전력 증폭기(HPA;high power amplifier)를 채용하고 있기 때문에 증폭단에서 많은 열이 발생된다. 따라서 과열로 인해 통신 시스템이 오작동하거나 사용수명이 단축되는 것을 방지하기 위해 효율적인 냉각 장치가 요구된다.Since outdoor communication systems such as base stations and repeaters employ a large number of high power amplifiers (HPAs), much heat is generated in the amplification stages. Therefore, an efficient cooling device is required to prevent the communication system from malfunctioning or shortening the service life due to overheating.

전기자동차(Electric Vehicle:EV)는 주로 배터리의 전원을 이용하여 AC 또는 DC 전기모터를 구동하여 동력을 얻는 자동차로서, 배터리전용 전기자동차와 하이브리드 전기자동차로 분류된다. 전기자동차는 배터리를 충전시켜 사용하게 됨에 따라 배터리를 충전시킬 경우 온도가 상승되어 배터리의 사용수명이 단축되므로 이에 대한 대책이 요구되는 실정이다.An electric vehicle (EV) is an automobile that uses an electric power of a battery to drive an AC or DC electric motor to obtain power, and is classified into a battery-dedicated electric vehicle and a hybrid electric vehicle. As the electric vehicle is charged with the battery, the battery temperature is raised when the battery is charged, so that the service life of the battery is shortened and a countermeasure is required.

따라서, 차량에 장착되는 배터리 또는 통신기기의 발열체로부터 발생되는 열을 쿨링 파이프의 냉각수에 의해 열교환시켜 방열시킬 수 있도록 쿨링 파이프가 인서트 성형되는 냉각모듈이 개발되고 있다.Accordingly, there has been developed a cooling module in which a cooling pipe is insert-molded so that heat generated from a battery mounted on a vehicle or heat generated by a communication device can be heat-exchanged by cooling water of a cooling pipe.

일 예로서, 쿨링 파이프가 인서트 성형되는 냉각모듈을 다이캐스팅에 의해 제조할 경우, 다이캐스팅은 고온(일 예로서 650℃ 정도를 말함)과 고압(일 예로서 700Kg/㎠ 정도를 말함) 상태로 용융 금속을 금형에 압입해서 성형하게 된다. 이로 인해 금형에 용융 금속을 주입시 주입 속도가 빠르면 내부에 설치된 쿨링 파이프의 형상 변형을 초래하여 불량품이 발생될 수 있고, 작업성이 떨어지므로 원가비용 상승을 초래할 수 있는 문제점이 있다.As an example, when a cooling module in which a cooling pipe is insert-molded is manufactured by die casting, the die casting is heated to a high temperature (for example, about 650 DEG C) and a high pressure (for example, about 700 Kg / Is pressed into a mold and molded. As a result, when the molten metal is injected into the metal mold at a high injection speed, the cooling pipe installed therein may be deformed, resulting in defective products, and the workability may be lowered.

특허출원 10-2015-0077013호에 제품 변형 방지 형개형 다이캐스팅 금형이 게시되어 있다.The patent application No. 10-2015-0077013 discloses an anti-deform die mold die casting die.

주형에 용융된 알루미늄을 캐비티(15)에 임의 압력으로 주입시 볼트(21)의 머리부(22) 돌출로 인해 용융된 알루미늄 흐름을 간섭하지 않도록 제1클램프(19) 또는 제2클램프(20)에 머리부(22)를 수용하기 위한 함몰부(23)가 형성될 수 있다.The first clamp 19 or the second clamp 20 is provided so as not to interfere with the molten aluminum flow due to the protrusion of the head 22 of the bolt 21 when the molten aluminum is injected into the cavity 15 at a certain pressure, A depressed portion 23 for receiving the head portion 22 may be formed.

탕구(13a)를 통해 용융된 알루미늄을 캐비티(15)에 임의 압력으로 주입시 쿨링 파이프(12)가 길이 방향으로 유동되는 것을 방지할 수 있도록 클램프(16)를 수용하기 위한 요홈(24)이 주형의 고정금형(13) 및 가동금형(14)의 밀착면에 각각 형성될 수 있다.A groove 24 for receiving the clamp 16 is formed in the mold 15 so as to prevent the cooling pipe 12 from flowing in the longitudinal direction when the melted aluminum is injected into the cavity 15 at a certain pressure through the sprue 13a, The fixed mold 13 and the movable mold 14, respectively.

전술한 바와 같이 주형을 이루는 고정금형(13)(하부금형을 말함) 및 가동금형(14)(상부금형을 말함)의 합형, 주형의 캐비티(15)에 용탕을 주입 및 응고, 고정금형(13) 및 가동금형(14)의 이형, 주물 주출 등의 전 단계가 자동화기기에 의해 수행되어 주물을 성형하는 기술내용은 본 기술이 속하는 기술분야의 당업자에게는 자명한 것이다. 일 예로서 주형의 일측에 설치되는 온도센서 또는 타이머에 의해 각각의 작업단계가 순차적으로 이루어지며, 주형의 온도 제어를 위해 히팅라인과 냉각라인에 공급되는 열량을 조절할 수 있음은 물론이다.The molten metal is injected and solidified into the cavity 15 of the mold, and the molten metal is injected into the cavity 15 of the stationary mold 13 (referred to as " upper mold " And molding of the movable mold 14, casting, and the like are carried out by an automation machine to form the casting, is obvious to those skilled in the art. For example, each of the operation steps may be sequentially performed by a temperature sensor or a timer installed on one side of the mold, and the amount of heat supplied to the heating line and the cooling line may be adjusted to control the temperature of the mold.

도 6을 참조하면, 본 명세서의 일 실시예에 따른 쿨링 파이프가 인서트되는 냉각모듈의 제조방법에 의하면,Referring to FIG. 6, according to the manufacturing method of the cooling module in which the cooling pipe is inserted according to the embodiment of the present invention,

발열체로부터 발생되는 열을 쿨링 파이프를 순환하는 냉각수와 상호 열교환에 의해 방열시키기 위한 쿨링 파이프가 인서트 되는 냉각모듈의 제조방법에 있어서,A manufacturing method of a cooling module in which a cooling pipe for inserting heat generated from a heating element by heat exchange with cooling water circulating through a cooling pipe is inserted,

S10에서와 같이, 고정금형(13) 및 가동금형(14)으로 이루어지는 주형(즉 금형을 말함)을 준비한다.A mold (i.e., a mold) comprising the stationary mold 13 and the movable mold 14 is prepared as in S10.

S20에서와 같이, 냉각수가 유입되는 냉각수 입구(10)와 냉각수가 배출되는 냉각수 출구(11)가 형성되고, 냉각수가 순환되는 직렬형 임의의 관로를 형성하도록 쿨링 파이프(12)를 제작한다.The cooling water inlet 10 into which the cooling water flows and the cooling water outlet 11 into which the cooling water is discharged are formed and the cooling pipe 12 is formed so as to form an arbitrary series pipe in which the cooling water is circulated.

S30에서와 같이, 주형의 내부에 형성되는 임의의 캐비티(15)에 쿨링 파이프(12)를 고정시키되, 캐비티(15)에 용융된 알루미늄(Al)을 가압에 의해 주입시킬 경우 쿨링 파이프(12)가 주입 압력에 의해 유동되지 않게 쿨링 파이프(12)를 클램프(16)에 의해 캐비티(15) 내부에 고정하게 된다.The cooling pipe 12 is fixed to an arbitrary cavity 15 formed inside the mold as in S30 and when the molten aluminum Al is injected into the cavity 15 by pressurization, The cooling pipe 12 is fixed to the inside of the cavity 15 by the clamp 16 so that the cooling pipe 12 is not moved by the injection pressure.

S40에서와 같이, 냉각수 입구(10) 및 냉각수 출구(11)를 주형 외부로 노출시킨 상태에서 쿨링 파이프(12)가 차지하는 공간을 제외한 캐비티(15)의 공간에 용융된 알루미늄을 채워 냉각모듈(A)에 쿨링 파이프(12)를 매립시키되, 캐비티(15)에 용융된 알루미늄의 주입 압력에 의해 쿨링 파이프(12)의 찌그러짐 등의 형상 변형되는 것을 방지할 수 있도록 게이트 퍼팅면이 쿨링 파이프(12)의 윗쪽으로 위치하도록 용탕을 주입시킬 수 있다.The molten aluminum is filled in the space of the cavity 15 except for the space occupied by the cooling pipe 12 in the state where the cooling water inlet 10 and the cooling water outlet 11 are exposed to the outside of the mold, The cooling pipe 12 is embedded in the cavity 15 so that the gate putting surface of the cooling pipe 12 is prevented from being deformed due to the injection pressure of molten aluminum in the cavity 15, The molten metal can be injected so as to be positioned at the upper side.

도 2에서와 같이, 고정금형(13)에 형성된 캐비티(15)에 쿨링 파이프(12)의 파이프(12a)를 안착시킨 후, 고정금형(13)에 가동금형(14)을 포개어 합형하여 탕구(13a)를 통해 용탕을 금형 내부로 임의압력으로 주입시키게 된다.2, after the pipe 12a of the cooling pipe 12 is seated in the cavity 15 formed in the stationary mold 13, the movable mold 14 is placed on the stationary mold 13, 13a to inject the molten metal into the mold at a certain pressure.

이때, 게이트의 퍼팅면이 파이프(12a)의 위쪽에 위치하게 되므로 용탕의 흐름을 간섭하지 않게 된다. 이로 인해 금형에 주입되는 용융 알루미늄의 주입 압력에 의해 파이프(12a)의 외형이 찌그러지는 등의 쿨링 파이프(12)의 형상 변형되는 것을 방지할 수 있다.At this time, since the putting surface of the gate is located above the pipe 12a, the flow of the molten metal is not interfered. This prevents the shape of the cooling pipe 12 from being deformed such as crushing the outer shape of the pipe 12a due to the injection pressure of the molten aluminum injected into the mold.

S50에서와 같이, 용융된 알루미늄을 냉각시켜 쿨링 파이프(12)가 인서트 된 냉각모듈(A)을 제조할 수 있다. 냉각모듈(A)은 차량 등에 장착되는 배터리 등의 외관에 따라 T자형(미 도시됨), 일자형(미 도시됨), 또는 이들을 조합(미 도시됨)시킨 형상을 갖도록 다양한 형태로 변형될 수 있음은 물론이다.As in S50, the molten aluminum can be cooled to produce the cooling module A in which the cooling pipe 12 is inserted. The cooling module A may be variously shaped to have a shape of a T shape (not shown), a straight shape (not shown), or a combination thereof (not shown) depending on the appearance of a battery or the like mounted on a vehicle or the like Of course.

이때, 냉각모듈(A)에 인서트 된 쿨링 파이프(12)의 용융된 알루미늄을 급속 냉각시킬 경우 온도 응력으로 인해 냉각모듈(A)의 내구성이 떨어질 수 있고 쿨링 파이프(12)와의 열 저항이 증가될 수 있게 되므로, 냉각모듈(A)의 용융된 알루미늄을 상온에서 서서히 냉각시키는 것이 바람직하다.At this time, when the molten aluminum of the cooling pipe 12 inserted in the cooling module A is rapidly cooled, the durability of the cooling module A may be deteriorated due to the thermal stress and the thermal resistance with the cooling pipe 12 may be increased It is preferable to gradually cool the molten aluminum of the cooling module (A) at room temperature.

도면에는 미 도시되었으나, 차량에 탑재되는 배터리, 또는 옥외 통신시스템의 중계기 등의 발열체를 냉각모듈(A)의 외측면에 밀착되도록 장착시킨 상태에서, 발열체로부터 발생되는 열이 냉각모듈(A)과의 접촉면을 통해 냉각모듈(A)에 전도되고 다시 쿨링 파이프(12)에 전도된다. 냉각수 펌프(미 도시됨)로부터의 냉각수가 냉각수 입구(10)를 통해 쿨링 파이프(12)에 공급되어 순환된 후 냉각수 출구(11)를 통해 배출된다.Although not shown in the figure, the heat generated by the heating element is transmitted to the cooling modules A and B in a state where the battery mounted on the vehicle or the heating element such as the repeater of the outdoor communication system is mounted on the outer surface of the cooling module A. To the cooling module (A) and then to the cooling pipe (12). The cooling water from a cooling water pump (not shown) is supplied to the cooling pipe 12 through the cooling water inlet 10, circulated, and then discharged through the cooling water outlet 11.

전술한 바와 같이 발열체로부터 발생되는 열을 쿨링 파이프(12)의 냉각수와 상호 열교환에 의해 흡수하여 방열시키는 기술내용은 당해분야에서 사용되는 구성에 속하는 것이므로 이들의 구성에 대한 상세한 설명은 생략한다.As described above, the technology for absorbing heat by mutual heat exchange with the cooling water of the cooling pipe 12 to dissipate the heat generated from the heating element belongs to the structure used in the related art, and thus detailed description of the structure is omitted.

여기에서, 전술한 본 명세서에서는 바람직한 실시예를 참조하여 설명하였지만, 해당 기술분야에서 통상의 기술자가 하기의 청구범위에 기재된 본 명세서의 사상 및 영역으로부터 벗어나지 않는 범위 내에서 본 명세서의 내용을 다양하게 수정및 변경할 수 있음을 이해할 수 있을 것이다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
